摘要
研究了RV-20E减速器的疲劳性能,获得了RV-20E不同曲轴热处理强化工艺下的载荷和寿命曲线;分析了提升RV-20E减速器疲劳寿命的曲轴最优表层组织和最优表层硬度,讨论了RV-20E减速器曲轴的失效模式和失效机制;以S-N理论和Miner理论为基础,结合RV-20E受力分析,提出了基于曲轴滚针轴承组件的RV-20E减速器的寿命参量,并对试验数据进行了比较分析。结果证明,该寿命参量有效关联RV-20E减速器的疲劳寿命,能够用于预测RV-20E减速器疲劳寿命。
Fatigue performance of RV-20E reducers is investigated experimentally herein;load and life curves of RV-20E with different crankshaft heat treatment strengthening processes are obtained.The optimum surface microstructure and optimum surface hardness of the crankshaft for improving the fatigue life of the RV-20E reducer are analyzed,and the failure mode and failure mechanism of the crankshaft of the RV-20E reducer are discussed.Based on the S-N theory and the Miner theory,and combined with the force analysis of RV-20E,the life parameter of RV-20E reducers based on the crankshaft needle roller bearing assembly is derived,and the test data is compared and analyzed.The analysis and comparison show that the life parameter can effectively correlate the fatigue life of RV-20E reducers and can be used to predict the fatigue life of RV-20E reducers.
